1912. Serial No. 701,784.

To all whom z'tmay concern:

Be it known that I, ARMAND JEAN AU- GUSTE Dnrniinns'sm, a citizen of theFrench Republic, and residing at 19 Rue des Entrepreneurs, Paris,France, have invented a new and Improved Aeroplane, of which thefollowing is a full, clear, and exact description. 1

My invention relates generally to aeroplanes and more particularlyconsists of improvements relating to the reinforcement and thesuspension and support of the frame.

Aero-planes provided with a car or cage for the accommodation of theaeronaut, together with the engine and the accessories, are well known,the body of the car consisting of a beam of suitable section carryingrings which serve as supports for an envelop or fabric; machinesprovided with a hull of stream-like form on the under side of the frameare also known.

According to the present invention the frame or fuselage consists of alatticed girder, a portion which is removed to accommodate the motor,together with the passenger seats, the frame being reinforced underneathwhereby the girder is strengthened where the lattice work has beenremoved, the surface thereof being rounded, thereby resembling a hullbut not intended in any way to serve as a boat. This hull which is belowthe front portion of the girder also serves as a means for theattachment of the suspension and landing devices; the latter is composedof rigid quadrilaterals made up of uprights secured to the hull,together with skids having wheels attached thereto by a flexibleconnection along with protecting crutches which form diagonals.

The invention is hereinafter describedwith reference to the annexeddrawings in which- Figure 1 is an elevation of the front part of theapparatus showing the suspension device; Fig. 2 is 'a section on theline 22. of Fig. 1; Figs. 3 and 4 show, in elevation and in sectionrespectively, and on a larger scale, the detail of the flexiblesuspension of- Fig. 7 is a sectional view showing the means forsuspending the hull.

The apparatus which is more full described in my co-pending applicationerial No. 602,902 of which this application is a division, consists of aframe or fuselage A, comprising a light lattice girder supporting a tailpiece and the rudders at its rear. The transverse -or cross bars m ofthe lattice girder are dispensed with in the front portion of saidgirder, in order to provide space to accommodate the motor andpassengers. A hull B, formed of sheets of wood or metal laid upon ribseasily detachable, is located beneath the front of the lattice girder atthe removed portion and is intended to reinforce the front of thefuselage and to increase its resistance to shocks transmitted by thefront suspension device. This hull thereby accommodates the aviators,theengine and the tanks, the cont-rolling means, etc, while maintainingthe reduced length and depth of this girder.

The fuselage is mounted upon a suspension device,(Figs. 1 and 2)comprising two protecting crutches or runners -A which form thediagonals'of rigid quadrilaterals made up of the frame or fuselage A,theuprights 0, D, and the landing skids E. The

' uprights C, D, are provided at the top with grooves in which areseated the cables or slings a passing beneath the hull and from side toside thereof. The hull B is also madefast to the upper parts-of the urights bymeans' of collars a mounted on t e uprights C, D, which collarsalso clam the cables 0 to the uprights and englag e lts a'ssing throughthe top of the ull. 'In t is way the parts C, A E,..D, are firmlysecured to and moved with the aeroplane. Two wheels F are mountedloosely upon'the axle G which is connected to the apparatus on one handin the forward direction by two radius rods 9, at g, upon the skids andembrace the axle by means of forks 9 (Fig. 3) and on the other handinthe vertical direction by means of rubber thongs 9 (Fig. 3) which passover rods 9 connecting the extremities of thearms of V-shaped clips gpinned upon the axle and upon the rods 9 of the collars g encircling theskids.v The tube which forms the axle is protected by a rubber ring h,thereby preventing shocks being communicated from the skids to the axle;the thongs y can be withdrawn or placed in position without thenecessity of detaching the wheels, such operation being uselage.

-frame constructed as a lattice right a and receives a tube a, the endsof which are overturned upon the edges of the socket; steel tie rods aare passed'throu h the tube, thereby giving rigidity to t e Having thusdescribed claim as new, and desire to secure by Letters Patent 1. Animproved monoplane comprising a girder having transverse bars exceptnear ts front end which is thus left free or unobstructed, a

hull secured underneath the girder at the 4 pointwhere a free space isprovidefl'in the latter, sa d hull thus constituting a downwardextension of the girder adapted to redrilled through together with thecorresponding upmy invention, I

ceive aviators and scribed.

2. An improyed monoplane comprising a latticed girder, four uprightssupporting said girder to which their upper ends are secured, and skidsarranged dlagonally with relation to the uprights, their front endsprojecting and being curved upward, as described.

3. In a nionoplane, the combination with a lattice girder, of two pairsof uprights, a hull arranged underneath the girder, and

operating devices as demeans for supporting the hull, the sameconsisting of slings passing under. the hull and attached to the top ofthe uprights as described.

In testimony whereof I have signed my name to this specificationin thepresence of two subscribing witnesses.
